2014-03-20	small test changes	Kathy Gray

2014-03-20	Fix type checking bug that was incorrectly unifying type variables, leading ↵	Kathy Gray
	function 'a id x = x to have type 'a 'b . 'a -> 'b
2014-03-20	Type bit[n] means bit[0..n-1]	Gabriel Kerneis

2014-03-20	Add missing GPR registers for Power example	Gabriel Kerneis
	Second instruction now executes (but probably not correctly, check arithmetic since we ignore exts). Next step is to implement bitwise_or.
2014-03-20	Remove work-around from interpreter, move it to power.sail	Gabriel Kerneis
	Two bugs are worked-around here: - missing cast to nat when a vector is wrapped in exts (exts is a no-op currently anyway, so we are discarding it) - missing cast (due to limited type-inference) in one if branch: type given explicitly.
2014-03-20	Fix default type env	Gabriel Kerneis

2014-03-20	More tests for implicit casts	Gabriel Kerneis
	The last test added in vectors.sail fails.
2014-03-20	Workaround missing casts for external calls	Gabriel Kerneis
	This patch should be reverted when the interpreter is fixed. The first instruction of main.bin is now executed. The second one fails, seemingly because of a similar missing cast issue (external function add receives register GPR1 as value).
2014-03-19	Fetch-decode-execute & init for power	Gabriel Kerneis

2014-03-19	Fix endianness	Gabriel Kerneis
	This will never end…
2014-03-19	Fix bug when reading register through a cast	Kathy Gray

2014-03-17	More coercions	Kathy Gray

2014-03-17	Revert broken vector handling	Gabriel Kerneis

2014-03-14	Support regbits read and write	Gabriel Kerneis
	No support for non-contiguous writes.
2014-03-14	Pretty-print subreg correctly	Gabriel Kerneis

2014-03-13	Make test_power compiling again	Gabriel Kerneis

2014-03-12	Remove automagic register initialization	Gabriel Kerneis

2014-03-12	Correctly type checking and interpreting accesses of register "fields". ↵	Kathy Gray
	Register-reading action isn't reading the subreg correctly still (seems to be making up a value though). Corrects but to vectors.sail and power.sail use of plus. (A new bug in power.sail is exposed using a binary operator with one value)
2014-03-11	Change treatment of type abbreviations so that name and full type are ↵	Kathy Gray
	available for field lookups of registers; this feature still not fully working.
2014-03-11	Exhibit bug in interpreter in vector test	Gabriel Kerneis

2014-03-11	More work on interpreter and Power model	Gabriel Kerneis

2014-03-11	Confusion between first index and vector length	Gabriel Kerneis

2014-03-11	Increase support for register "field" accesses; there is now a bug in how ↵	Kathy Gray
	run_interp handles SubReg register forms.
2014-03-07	Treat registers as values when not being actively read or written to, so ↵	Kathy Gray
	that we can have a vector of registers for example. Also, register types can be explicitly referenced.
2014-03-07	Add default types to the initial env for provided functions	Kathy Gray

2014-03-04	Minimal power model to run hello world	Gabriel Kerneis
	Crashes because register initialization is missing.
2014-03-04	More polymorphism for addition	Gabriel Kerneis

2014-03-04	Various deinfix bugs	Gabriel Kerneis

2014-03-03	new test file	Kathy Gray

2014-03-03	Fixing assorted bugs. Adding ability to put a type on the identifier being ↵	Kathy Gray
	assigned to in assignments.
2014-03-01	Fix printing bug on vector slicing that caused only one element to ever be ↵	Kathy Gray
	sliced
2014-02-28	Fix endianness	Gabriel Kerneis
	In fact, increasing order is big-endian, not little-endian. This is good news for us, because it means we do not need any switch for the POWER spec.
2014-02-28	Do not build power test by default	Gabriel Kerneis

2014-02-28	Fetch-decode POWER interpreter	Gabriel Kerneis
	Many limitations and bugs currently, but loads binary and decodes opcodes correctly (using endianness hacks). Disabled in the default test suite (but still compiled), run "make test_power" to try it.
2014-02-28	Load ELF sections to virtual memory addresses	Gabriel Kerneis
	Roughly 110KB/s (~5 seconds to load "hello" test).
2014-02-28	Correct bug in parsing and handling a['a:'b] types	Kathy Gray

2014-02-27	Fix error to constructor pattern matching	Kathy Gray

2014-02-27	Load POWER binary into interpreter's memory	Gabriel Kerneis

2014-02-27	Partial fix for to_vec_inc/to_vec_dec	Gabriel Kerneis
	Lem's word library does some dark magic because of its assumption that words represent signed integers. Therefore, it is unreliable to truncate words, as well as to use the internal representation. boolListFrombitSeq seems safe for our purposes, though (provided the bitseq has been created with an infinite length from a positive integer).
2014-02-27	More flexible test execution	Gabriel Kerneis
